Exclusive activation for writing.

<p>Areas significantly activated for writing versus tapping (p<0.05, FWE corrected) with exclusive mask for zigzagging-tapping (p<0.001 uncorrected). <b>a).</b> Sagittal and coronal view of clusters (SMA = supplementary motor area; PMd = dorsal premotor cortex; SPC = superior parietal cortex; IPC = inferior parietal cortex; PMv = ventral premotor cortex). <b>b</b>). Time courses extracted from SMA (sphere centered on [−8 2 50]; see detailed statistics in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0067931#pone-0067931-t003" target="_blank">Table 3</a>) during the nine tasks (RH = right hand; LH = left hand; RF = right foot; w = writing; t = tapping; z = zigzagging).
